Manufacturers of mushrooms are increasingly selective regarding the machinery installed in their cellars: they want to know more about the processes that occur during growing and have control over the measurements in a larger number of locations within a cellar and measure additional specifics — e.g. air flow speed around the growing shelves and oxygen concentration.
To meet such growing demands, the LB-762-IO module was devised with additional interfaces — measurement inputs and control outputs to popular LB-762 air-conditioning regulators. The LB-762-IO module takes the form of an additional insert (electronics board), installed inside the LB-762 housing, over the main board of the LB-762 regulator. The LB-762-IO module may be integrated in every LB-762 regulator, whenever the user feels that the number of regulator interfaces has become insufficient.
The illustration features the block digram of the LB-762 regulator for a mushroom-growing cellar, together with an additional module of LB-762-IO interfaces.
To the left of the block diagram, a basic set of inputs for measurement probes of the LB-762 regulators are shown; they enable the connection of:
The basic set of outputs of the LB-762 regulator are the outputs for connecting:
To the right of the block diagram, an additional set of inputs for measurement probes of the LB-762-IO extension module are shown; they additionally enable the connection of:
The additional set of outputs of the LB-762 regulator are the outputs for connecting:
Current design of measuring probes ensures stable measurement results. In order to differentiate, the new psychrometric sensors, and probes for substrate temperature and air-conditioning feature colour-coded outputs, thus they should be connected to the regulator’s board as shown in the figure. Particular attention should be exercised in order not to reverse the terminals of temperature probes (T and GND terminals). An illustration showing the input terminals of the main board of an additional LB-762-IO extension module is presented alongside.
Controlling the extension module requires the installation of the new version of the regulators’ internal software (the minimum requirement is the LB762V1_firmware_2.1.1.fw version) and software for the SERVER and CLIENTS stations on all Windows PCs operating with the system minimum: lbx-2.14-setup.exe).
Following the increased number of sensors connected to the LB-762 mushroom-growing cellar climate regulator equipped with an additional LB-762-IO insert, the LBX software has been updated in a way allowing the complete set of current measurement results to be displayed on the screen (see alongside).
The calibration and operation parameters of the LB-762 regulators with the LB-762-IO module may also be set-up via the LB-765 remote controller. Detailed operating instructions on how to use the regulator with the remote control is provided in the User Instructions.
All questions and remarks concerning the functioning of the LB-762 software that controls in mushroom-growing cellars, suggestions for further development of the software and user experience issues as well as their requirements for growing should be reported to al [at] label.pl.
We provide free-of-charge assistance in the correct configuration of mushroom-growing cellar regulators. For this reason it is necessary to establish an Internet connection for a given mushroom-growing cellar, so that we — with a phone call — are able to observe the regulators’ functioning (charts) and correct their settings. Feel free to phone us for more details.
